May 7, 189370. Serial No. 450,513.

This invention relates to new and useful improvements in resilient furniture slat suports. p It is the principal object of my invention to provide for upholstered furniture such as chairs and davenports, bottom slats that are hingedly secured at their front ends to the Vchair frame and which are supported at their rear ends by vertical helical springs attached to said frame. These helical springs connected between the rear ends of the slats and the chair frame at points above them, allow a free vertical movement of the slats within the elastic limits of the springs, thereby providing an extremely resilient seat where the weight is greatest. Such a seat is most beneficial to the occupant, and the helical springs neverpermit it to become solid. Another object of the invention is to elimi- 1- nate the webbing commonly used to support the springs of upholstered furniture.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawingillustrating my invention, Figure 1 is a sectional view through the frame of a conventionalA upholstered chair. Figure 2 is a bottom view of the frame of the same. And Figure 3 is a detail view of my spring suspension means for the slat bottom of the chair.

Referring to the accompanying drawing for a detailed description of my invention,

vthe numeral 1 designates an upholstered liv- In Figure 1 the numeral 7 designates aV seat cushion which is supported by a fabric bottom 8 connected between the end members 3, 3. This fabric bottom 8 rests upon the -1 usual cushion supporting springs 9, of which nine are shown. The outer ones of these springs 9 are secured at their top portions to Y a square steel-wire frame 10.

The bottom portions of the cushion springs 9 are resiliently supported by slats 11. p These The nuslats'are supported at their frontends by spring angle clips 12 whose horizontal portions are secured to the `bottom'surfacesof the slats by nails 13 orother suitable fastening elements. The `vertical parts of these angle clips are nailed or otherwise firmly secured to thefront end rai-l 3 ofthe chair.

Secured to the front end rails 3, a short dis- PATENr o1=l=rcr.f A

tance above the front ends of the slats 11, is

a horizontal member 14 that acts as a stop to prevent damage' to these slats, if they are moved inwardly during the packingof the chair. v

The free or rear ends of the slats 11 are supported in the following manner to permit them to yield most at those points where the weight which theysupport is the greatest.

Attached tothe bottom surfaces of the rear ends of the slats 11 by nails 15 or other suitable fastening elements, are spring angle clips 16 having upwardly inclined portions that are apertured to receive the hook ends of helical springs'17. The upper hook ends of these springs are received by the inner downwardly inclined apertured ends of spring clips 1S that are attached to the top parts of the rear end rails 3 by nails 19 or other suitable fastening elements.

When a downward pressure is exerted upon the rear ends of the slats 11, by the greater weight which the occupant imposes upon the rear part of the cushion 7, they will yield within the elastic limits of the helical springs afforded by these slats with no fixed members below to be engaged by them when a person is being seated in the chair, nor'will they become a solid support through long and intensive use.

Hingedly secured at their front ends to the front rail 3 and free to move vertically at their rear ends within the elastic limits of the .17. A support of great resiliency is thus Y helical springs 17, the slats 11 are an extreme- -V ly yielding support for the'cushion springs 9 upon whichthe cushion 7 rests. Under the front end of this cushion a padding 18 is placed upon the fabric bottom 8.

Having described my invention, I claim: 1. In an article of the type described, the combination with a pair of end rails, of slats horizontally disposed between and below the tops of said rails, spring angle clips for securing the front ends of said slats to the front end rail, and helical springs secured to the rear ends of said slats and .inclining upwardly for attachment to the rear endrail to resiliently support the slats.

2. In an article of the type described, the

combination with a pair of end rails, of slats horizontally disposed 'between said? rai-lis and below the tops thereof, means for securing the front ends of said slats to the front end Y rail, spring angle clips secure-d over the top of the rear end rail and. having .downwardly inclined inner end portions, spring angle secured-to the bottom portions :of the rear end-sott `the slats and having upwardly' inclined rear end. portion-s, and long inclined coil. springs: .secured between 'the inclined 4ends orf the spriiaigclips.

In. testimony whereof I have hereunto set my hand this day of lVlay 1930. Y
